RUDOLF LOEB, OF CAMDEN, NEW JERSEY.

EMBROIDERING-MACHIN E Application filed September 25, 1900.

To all whom it may concern:

Be it known that I, Runonr Lose, a citizen of the United States, and a resident of Camden, New Jersey, have invented certain linprovements in Embroidering-Machines, of which the following is a specification.

Hy invention consists of certain improvements in that class of embroidering machines known as round stitch machines, or embroidering machines of the Cornely type; the object of my invention being to provide special mechanism for rotating the needle and its spindle and the nipple; to provide a channel through the sleeve of the needle spindle and nipple guide for the passage of the einbroidering thread to the point where it is sewn to the fabric; to facilitate the delivery of the thread to this channel; to provide for a firmer mounting for the pantograph lever in order that the movement of its foot may be true and steady; to give an intermittent feed to the embroidering thread whereby it may be readily sewn down to form the predetermined design, and to insure the proper tension for said thread so that the work will not appear drawn or uneven.

A further feature of my invention consists in maintaining a constant supply of embroidering thread at hand, ready for continuous use.

Other features of my invention, shown in the accompanying drawings, will be more clearly pointed out hereinafter, reference being had to said drawings, in which:

As I have stated, the improvements forming the subject of my invention have been ap plied to a round stitch eiiibroidering machine of the Cornely type, hence it is to be understood that no change has been made in the driving mechanism of the same, except in the mechanism carried by the thread spindle for rotating the same continuously. The transmitting mechanism for operating said thread spindle, the needle spindle and the nipple spindle, being the same as that used heretofore, as is also the mechanism for operating the pantograph lever.

1 is the nipple spindle, controlled, so far as rotative movement is concerned, which movement is intermittent by the pantograph lever, and only rotated when the pantograph handle is moved.

2 is the thread spindle, driven, by means of the gear wheels 3 and 3 and the intermediate wheel 4, in one direction continuously. In order to give the nipple spindle 1 the desired intermittent rotating movement through the operation of the pantograph handle, the following mechanism is employed: The gear wheel 3 is provided with a hub 5 on which is mounted the gear wheel 6, said gear wheel having two sets of teeth, 6 and 6 Engaging the teeth 6, is the gear wheel 7 carried by a suitable shaft 8, and driven by means of the bevel gears 8 and 8*, from the pantograph handle through the usual transmitting mechanism.

Engaging the teeth 6 of the gear wheel 6 is a pinion 9 carried by a frame 10 which is rotated with the thread spindle 2 independently of the nipple spindle 1. The pinion 9 is disposed eccentrically to the frame 10. At the upper end of the stud 11 carrying this pinion 9, is another pinion 9 engaging a gear wheel 12 splined to the nipple spindle 1; such arrangement being a form of the well known planet gearing. By this means, the nipple spindle 1 will be given an intermittent movement independent of the regular continuous rotary movement of the frame 10 and thread spindle 2, which moves around the spindle 1 and carries the channel or conduit for the passage of the embroidering thread w to the nipple where it is sewn to the fabric.

The embroidering thread is introduced into the channel or passage 13 in the upper portion of the needle spindle extension 14, passes down through said channel and out through the slot 15 in the nipple spindle extension 16 and is directed to the channel or conduit 17 carried by the frame 10. The thread then passes to the channel 18 in the thread spindle 2 surrounding the nipple spindle 1; emerges from said channel at 19 and is then directed over one or more of the usual fingers 20, which serve to give a certain amount of tension to the thread, to the pantograph foot 21 which guides it around the nipple 22 to form the design, which design is sewn in the usual manner by the needle 23 with the'thread from the usual looper located beneath the bed plate of the machine.

The needle spindle extension 14: is aranged to be moved up and down in the manner usual to this class of machines, but I prefer to arrange the vertically movable member 24 providing such movement above the head of the machine, so that the fork 25 of the same will engage the recessed portion 26 of the needle spindle extension. The nipple spindle extension 16 surrounds the needle spindle extension 14, and a rotative movement is imparted to this nipple spindle extension by means of the forked arm 27 having a collar 28 by means of which it is secured to the nipple spindle extension. This collar is preferably split as shown in Fig. 7, and clamped to the nipple spindle extension by means of a screw 29. The lower forked end of the arm 27 is engaged by a pin 30 carried by an arm 31 secured to the frame 10 by the screw bolt 82. By this connection, provision is made for the simultaneous rotation of the nipple spindle extension and the needle spindle extension, and for the vertical movement of the nipple spindle extension.

The upward movement of the needle bar 23 and its spindle 14 is accomplished by the engagement of a pin 63 carried by a cam (53 on the shaft 63 with the movable member 24, and this movement takes place in advance of similar movement imparted to the nipple spindle by an arm 24 engaging a collar 25 of the nipple spindle extension, but the downward movement of these parts is in the reverse order. The arm 2% is carried by a slidable member 24:", and a spring 24- is provided for returning said slidable member to its lowermost position. To raise this member 24* and thereby effect the upward movement of the nipple spindle, I provide a bell-crank lever pivoted at 249; one arm 2& of said lever lying in the path of the cam 63 while the other arm 24 has a pin 21 for engagement with a pin 24* carried by said slidable member 24 To limit the downward movement of the nipple l spindle extension, I mount a collar 38 on the nipple spindle 1, as clearly shown in Figs. 1, 2, 8 and 11.

The upper end of the nipple spindle 1 is slotted at 34, as clearly shown in Fig. 2, and adapted to this slot is a projection 35 car ried by the needle spindle 14*, whereby said needle spindle may be rotated by said nipple spindle; these parts being controlled, of course, by the pantograph mechanism.

At the extreme upper end of the nipple spindle, a shoulder or collar 36 is provided, by means of which it is retained in the nipple spindle extension 16, said nipple spindle being introduced into the machine from the top. The needle spindle is also provided with a collar or shoulder 37 by means of which it is held to the needle spindle exten sion 1 1 and can move with the same; said collar can be slipped into a slotted yoke 38 at the bottom of said extension. The needle spindle 1 F and needle-bar 2' a are held in engagement with each other by means of the thumb screw 39, which passes through the projection and contacts with said needlebar. I prefer to make the nipple spindle in two parts, as shown in Fig. 2, and these parts are connected together by threading one into the other, as seen at 40.

lVith the form of driving and operating mechanism for the nipple spindle, just described, the ordinary form of pantograph lever is employed, such for instance as shown in Fig. 8. This form of lever, however, would interfere with the improved mechanism surrounding the nipple spindle. Moreover, the supporting bearing for this style of pantograph lever is objectionable, as it must be kept loose owing to the peculiar movement of the pantograph lever. With the form of pantograph lever shown at 41 in Fig. 8, the loose bearing is necessary as the foot 21 of the pantograph is continuously changing its movement. This movement is always in the nature of a step-bystep motion, but its direction varies according to the design of embroidery to be followed. This pantograph foot moves the fabric in order to effect the proper disposition of the embroidering thread sewn in the same. To obviate the loose mounting of the pantograph lever, I have devised the improved form of support shown in Figs. 9, 10 and 12. In these views 41 represents the pantograph lever which is hung to one side of the nipple spindle extension 16. Theo retically this mounting is wrong, for the reason that when the foot 21 of said lever is making its step-by-step movement as the lever is operated, the under surface of said foot is constantly changing from the hori zontal. In practice, however, the movement of the foot is in such a limited area that this change of plane is not material. The lever i1 is hung from a block 42 supportedby the journal or pivot pins 4:3 which are carried by arms 14 mounted on the slides 45. Col lars 46 are interposed between the block 12 and the arms 1% so that said support will be solid at all times. The block 452 swings on the pins 43, this arrangement providing for movement of the pantograph lever in one direction. To provide for the movement of said lever in the opposite direction, the upper end of the same is forked at 4:7, and this forked portion is secured to the block 42 by means of the screw pin 18. This method of hanging the pantograph lever gives it a substantially universal joint or connection. The slides are connected together by the cross-piece 49, held in place by suitable screws 50.

In all embroidering machines of the class to which my improvements have been applied, no provision has been made for a constant supply of the embroidering thread. This thread is usually bulky, and the embroidering machines hitherto constructed have only been arranged to carry small spools of the same, which must be constantly renewed. This constant renewal is a source of much delay in efiecting the embroidering desired, so much so, that in ordinary embroidering machines the means for I supplying thread to the nipple is such that a new spool must be added about every five minutes. This it may be readily understood, is both expensive and annoying, as the thread has to be placed in the passage in the nipple spindle extension and conveyed through the various channels in the head of the machine to the sewing needle, each time a new spool is set in place. Moreover, the most important point lies in the fact that each time a spool runs out and a new thread is started on the fabric, a defect is made in the embroidery which must be remedied by hand sewing, and at the same time, the end of each new thread must be tacked down.

lVith an embroidering machine of this character, constructed as I have arranged it, however, a supply of thread may be carried by the same and continuously fed to the sewing needle, such supply lasting an entire day, so that the machine need be threaded but once a day. In using the small spools of embroidering thread moreover, the tension changes just as soon as the thread begins to run off the spool, so that the first part of the embroidery will be loose, while the last part will be tight. hen the thread is delivered in the manner devised by me, the tension is constant, the thread being sewn down uniformly. I also provide means for feeding the embroidering thread readily to the sewing thread so that there will be no tendency of the embroidery to show a drawn or pulled appearance.

In Fig. l, I have shown special means for delivering the embroidering thread to the channel or passage 13 in the needle spindle extension, and in Figs. 14 and 15, I have shown another device for effecting the same result. In Fig. 1, a spool 52 of embroidering thread is suspended directly over the nipple spindle 1 of the machine, so that the center of the axis of the spool is the same as the center of the vertical axis of the needle bar.

The thread spool 52 is supported and rotated in the following manner: Mounted on the arm 53 of the machine and secured thereto by means of bolts 54, is a standard 55, projecting some distance above said arm 53. This standard has an arm 56 projecting at right angles from the same, and the thread spool is carried by a bracket 57, hinged at 58 to said arm 56, and having a thumb screw 59 whereby it may be retained in its proper position with relation to the needle bar of the machine. The standard has a shaft 60 extending through the same, and this shaft carries at its lower end a worm wheel 61 which receives its motion from a worm 62 carried by the main driving shaft 63. At the upper end of the shaft 60, a bevel gear wheel 64 is mounted. This bevel wheel meshes with a bevel pinion 65 carried by a short shaft 66 located within the arm 56, and at the opposite end of this short shaft a bevel wheel 67 is carried, meshing with a similar bevel wheel 68 carried by the thread spool spindle 69, whereby said spool is driven. The spool is supported in place by the nut 70 having a plate 71, said nut being adapted to the end of the spindle 69.

The spool 52 is loosely mounted on the spindle 69 and receives its movement by frictional contact therewith. For the purpose of retarding this movement, should it be desirable at any time, I provide a spring finger 72 carried by the arm 56 and adapted to engage the upper flange of the spool. This spring finger will also serve to stop the rotation of the spool when the movement of the spindle ceases. Provision may be made for increasing or diminishing the pressure of said spring. If desired, however, the connection between said spool and its spindle may be made positive, and the gearing so timed that the thread will be delivered as required.

To renew the spool after the thread from one has been used, the thumb screw 59 is released, permitting the swinging of the bracket 57 from its hinge at 58. The nut 70 is then unscrewed, when the empty spool may be removed from the spindle 69, and a full spool put in place. The nut is then secured to the end of the spindle, and the bracket returned to its normal position and held by the set screw 59.

A thread guide comprising a vertical stem 7 3 is carried by the upper end of the needle spindle extension 14L, and this stem is so arranged that it may be moved. during the rotation of the needle spindle extension for the purpose of giving the embroidering thread an extra pull during every revolution of the nipple in order that the thread may be fed to said nipple and the sewing needle in proper shape. The stem '73 is pivotally mounted on the end of an arm 7-]: which pro jects from a ring mounted on the upper portion of the needle spindle extension 1%, and secured thereto by a screw 76. The stem 73 is movable in one direction only, and has a portion projecting below the arm 741-, so that such movement may be effected by the engagement of said projecting portion with a cam 77 carried by the vertically moving member 24. A foot 78 is carried by the stem 73 for the purpose of preventing any inward movement of said stem, and a spring 79 is employed to maintain said stem in the vertical position.

In Figs. 1a and 15, I have shown another form of spool support, in which a yoke 80, adapted to be carried by the bracket 57, serves as a support for a spool 53*. For the purpose of guiding the thread, I secure to this yoke a curved arm 81, having an eye 82 for the passage of the thread, disposed directly above the needle bar of the machine. As the thread leaves this spool, it contacts with a curved arm 83 secured to the head of the machine, and arranged to project into the path of the embroidering thread as it is delivered from said spool. The curved portion 84 of this arm is so arranged tha as the spool yoke is revolved and the thread delivered by the same contacts with said curved arm, an extra pull will be given the same, as the fabric at this point in the operation of the machine, is being held, either by the foot of the pantograph lever or by the nipple. By this means, the movement of the spool yoke being timed, a sufficient quantity of embroidering thread to supply the sewing needle and thereby effect the necessary embroidery, is pulled forward by the curved arm at every revolution of the spool yoke. In this form of thread carrying device, the thread is pulled from the spool as it is used, the spool rotating by such action. To prevent too rapid rotation of the spool, I provide a spring finger 7-2 in engagement with the flange of said spool, and for the purpose of adjusting the tension of this spring, I arrange the set screw 85.

The shaft (30 carried by the standard 55 is provided with a worm wheel ()1 which derives its motion from a worm (32 carried by the main driving shaft 63. This form of driving mechanism for the shaft (30 is preferred, as the stopping of the main driving shaft will act to stop the counter shaft (36 soon as said driving shaft comes to rest; the teeth of the worm wheel 61 jamming in the worm 62.

sneeze iVith this class of embroidering machines, it is often desirable to make that style of embroidery known as underlining, such for instance as shown in Fig. VII, of the patent to E. & It. Cornely, No. 466,889, patented January 12, 1892. For this purpose an extra thread must be delivered to the sewing needle in such position that the embroidering thread guided by the nipple may be wrapped around the same, the whole being sewn in the usual manner. For the purpose of introducing such additional thread, the needle bar 14 is provided with a passage 86 as shown in Figs. 2, 3, 4, 5, 6 and 7. As this additional thread must be directed so that it will not become entangled with the embroidering thread, the spindle 69 of the spool 53 may also be provided with an opening 86 extending through the same, for the passage of said additional thread.

\Vhile I have shown the improvements forming the subject of my invention as applied to a round stitch machine of the Cornely type, it will be understood that with but slight modification, such improvements may be applied to all forms of embroidering machines.
